Some resource packs I made. Requires optifine. Turn on custom colors in optifine settings for it to work. I recommend turning dynamic lighting on for the best effects. Use it for challenges or as a budget shader. Should work in 1.16.1+. If it says outdated pack don't worry about it. It should work.
I used vanilla-lightmap by Nixel as a base: https://www.planetminecraft.com/texture-pack/for-resource-pack-developers-vanilla-overworld-lightmap-recreation/
DIFFERENCES:
Pure Darkness: Pitch black. Can only see with light sources.
Hardcore Darkness: You can see in the day, but night and caves are pitch black.
Cinematic Darkness: Pure Darkness except you get a little bit of light at sunrise and sunset.
Inverse Darkness: Pitch black day, bright night.
